JP, 2017-013895, A

  By the way, in the dispenser of Patent Document 1, since the discharge holes are exposed, it is necessary to separately cover the dispenser with a protective cap or the like so that dust and the like do not adhere. However, the protective cap is cumbersome because it needs to be removed and attached after each use. It is hard to use especially with one hand.

  Then, this invention aims at provision of the discharge member which can be used easily also with one hand, and an aerosol product using the same.

  The discharge member of the present invention covers the discharge nozzles 2, 21 and 22 attached to the aerosol valve 130 and the discharge nozzles 2, 21 and 22, and operates the aerosol valve 130 via the discharge nozzles 2, 21 and 22. The operation caps 3, 31, 32 are slidable along the discharge nozzles 2, 21, 22 and the discharge nozzles 2, 21 are operated before the aerosol valve 130 is operated. , 22 are provided with the openings 3 d, 32 d for causing the projection 22 to protrude to the outside.

  Further, it is preferable that the peripheries of the openings 3 d and 32 d be set as skimming surfaces 3 g and 32 g for removing the discharged matter discharged from the discharge nozzles 2, 21 and 22 and adhering to the discharge nozzles. Moreover, it is preferable that 32 g of skimming surfaces are comprised by the front-end | tip of the brush 32b.

  The discharge nozzles 2, 21 and 22 have an axially extending internal passage 2d, a closing portion 2e for closing the tip of the internal passage 2d, and a plurality of discharge holes 2f opened laterally of the internal passage 2d. Also good. In this case, the inner peripheral surface of the discharge hole 2f may be provided with a pair of side surfaces 2g and 2h for controlling the discharge direction of the discharge material discharged from the internal passage 2d to the outside through the discharge hole 2f.

  The aerosol product of the present invention is characterized by comprising an aerosol container 110, foamable contents filled in the aerosol container 110, and any one of the above-described discharge members provided in the aerosol container 110.

  In the discharge member of the present invention, since the discharge nozzle is covered by the operation cap, it is not necessary to separately attach a protective cap. Moreover, since the operation cap is provided with the opening part for making a discharge nozzle project outside, it can be used, without removing an operation cap.

  If the periphery of the opening is a discharge surface from the discharge nozzle, and the discharge material attached to the discharge nozzle is skimmed off, the discharge object is moved to the removal surface when the operation cap returns to the original position. It can be done.

  If the scooping surface is constituted by the tip of the brush, since the discharge material adheres to the tip of the brush, it is easy to use because it can be applied to the object as it is.

  If the discharge nozzle includes an axially extending internal passage, a closing portion closing the tip of the internal passage, and a plurality of discharge holes opened on the side of the internal passage, the discharge material has a complicated shape, The discharge thing excellent in the designability is obtained.

  If the inner peripheral surface of the discharge hole has a pair of side surfaces for controlling the discharge direction, the discharge direction of the discharge material can be controlled. For example, the discharge material is formed into a soft cream shape which swirls around the discharge nozzle. You can also

FIG. 4A is an end view and FIG. 4B is a cross-sectional view showing a state in which the contents are discharged, showing still another aerosol product of the present invention.

  Next, the aerosol product of the present invention will be described based on the drawings. As shown in FIG. 1, the aerosol product 100 according to the present invention includes an aerosol container 110, foamable contents to be filled in the aerosol container 110, and the discharge member 1 attached to the aerosol container 110.

  The aerosol container 110 includes a container body 120, an aerosol valve 130 for switching communication between the inside and the outside of the container body 120, and a mounting cup 140 for attaching the aerosol valve 130 to the opening of the container body 120. The container body 120 includes a cylindrical body 120a, a tapered shoulder 120b extending from the upper end of the body 120a, a cylindrical neck 120c extending from the upper end of the shoulder 120b, and a bead 120d at the upper end of the neck 120c. And a bottom (not shown) that closes the bottom of the trunk 120a. Further, a concave groove 120e continuous in the circumferential direction is formed between the bead portion 120d and the neck portion 120c. The aerosol valve 130 includes a stem 130a for discharging contents, a stem rubber for switching between communication and disconnection between the stem hole of the stem 130a and the inside of the container body 120, a spring for urging the stem 130a upward, and a stem 130a. The valve housing is housed in a vertically movable manner, and it is known that the stem hole is opened by depressing the stem 130a and closed when the depressing is stopped. The peripheral edge of the mounting cup 140 is engaged with the bead portion 120 d of the container body 120.

  Effervescent contents include, for example, skin care products such as face wash, cleaning agent, bath agent, moisturizing agent, cleansing agent, sunscreen, skin lotion, shaving agent, depilatory, antiperspirant, disinfectant, pest repellent, etc. Medicines, shampoos, treatments, styling agents, hair care products such as hair dyes, food products such as whipped cream, household products such as deodorants, fragrances, insect repellents, and germicides. However, it is not necessarily limited to these applications.

  This foamable content is composed of a stock solution containing the active ingredient of the application and a propellant for foaming the stock solution, and as the propellant, for example, aliphatic carbonization having 3 to 5 carbon atoms such as propane, butane, pentane and the like Examples thereof include hydrogen, liquefied gases such as hydrofluoroolefin and dimethyl ether, carbon dioxide gas, and compressed gases such as nitrogen. Among them, surfactants containing fatty acid soap and the like, higher alcohols, solid oils such as higher fatty acids and the like are contained in the stock solution, from the viewpoint of being excellent in foam formability and shape retention, and making the foam into a desired shape. It is preferable to use liquefied gas as a propellant.

  The discharge member 1 covers the discharge nozzle 2 attached to the stem 130 a of the aerosol valve 130 and the discharge nozzle 2 and is slidable along the axial direction of the discharge nozzle 2. The operation cap 3 to operate, the biasing member 4 which returns the operation cap 3 to the original position before operation, and the cover member 5 which covers the upper end of the aerosol container 110 are provided. However, the biasing member 4 and the cover member 5 need not necessarily be provided.

  The discharge nozzle 2 has a mounting portion 2a mounted to the stem 130a, a nozzle portion 2b provided at the upper end of the mounting portion 2a, and a flange portion 2c projecting radially outward from between the mounting portion 2a and the nozzle portion 2b. It is divided roughly. As shown in FIG. 2B, an internal passage 2d extending in the axial direction of the discharge nozzle 2 is provided from the mounting portion 2a to the nozzle portion 2b. The upper end of the internal passage 2d is closed by a closing portion 2e provided at the tip of the nozzle portion 2b. On the other hand, the nozzle portion 2 b is provided with a plurality of discharge holes 2 f opened on the side of the internal passage 2 d. Therefore, the contents supplied from the stem 130a to the internal passage 2d are discharged from the discharge holes 2f to the outside.

  The discharge holes 2 f will be described in more detail. As shown in FIG. 2C, four discharge holes 2 f are provided at substantially equal intervals around the central axis of the nozzle portion 2 b. The inner peripheral surface of the discharge hole 2f is provided with a pair of side surfaces 2g and 2h for controlling the discharge direction of the discharge material discharged from the internal passage 2d to the outside through the discharge hole 2f. Specifically, the nozzle portion 2b is thick, and from the inlet 2i of the discharge hole 2f (the boundary between the discharge hole 2f and the internal passage 2d) to the outlet 2j (the boundary between the discharge hole 2f and the outer surface of the nozzle 2b) A control passage CP of such a length as to control the discharge direction of the foam which is the discharge is formed by the pair of side surfaces 2g and 2h which continues up to the end. For example, the horizontal length L1 of the control passage CP is longer than the horizontal width W1 of the inlet 2i of the discharge hole 2f. Further, the pair of side surfaces 2g and 2h draw arcs from the inner passage 2d to the outside, and the arcs are curved in the same direction. In other words, the control passage CP is curved. By changing the curvature and length of the pair of side surfaces 2g and 2h, the discharge direction of the discharge material can be controlled.

  Returning to FIG. 1, the operation cap 3 has an appearance in which cylinders having different diameters are stacked in the axial direction. The inside is hollow, and the inner diameter of the lower cylindrical body 3 a is larger than the outer diameter of the cover member 5. Further, the inner diameter of the upper cylindrical body 3 b is larger than the outer diameter of the flange portion 2 c of the discharge nozzle 2. Furthermore, an opening 3d for causing the nozzle portion 2b of the discharge nozzle 2 to protrude outside (outside the operation cap 3) is provided at the center of the top plate 3c having a substantially circular shape in plan view. Therefore, even if the operation cap 3 is depressed downward, the predetermined distance can depress only the operation cap 3 without interfering with the discharge nozzle 2. When the operation cap 3 is pushed down to a certain distance, the top plate 3c that closes the upper end of the upper cylindrical body 3b abuts on the flange portion 2c of the discharge nozzle 2 so that the aerosol valve 130 can be operated via the discharge nozzle 2 (See the dashed line in FIG. 1).

  The biasing member 4 is a coil spring. An upper end side of the biasing member 4 is extended downward from a ring-shaped second top plate 3e connecting the upper end of the lower cylindrical body 3a of the operation cap 3 and the lower end of the upper cylindrical body 3b. The lower end side is attached to the cover member 5. The cover member 5 is substantially cylindrical and attached to the container body 120 so as to cover the upper end of the container body 120. Specifically, the lower end of the cover member 5 is engaged with the concave groove 120 e of the container body 120. Further, from the inner peripheral side of the cover member 5, an arm portion 5a is extended in the radially inward direction. On the upper surface of the arm 5a, a receiving groove 5b having a ring shape in plan view for receiving the biasing member 4 is provided.

  Before use (pre-operation), the aerosol product 100 of the above configuration is in a state in which the operation cap 3 covers the discharge nozzle 2. In use, for example, a finger is put on the second top plate 3e of the operation cap 3 and pushed downward. As described above, only the operation cap 3 slides downward along the discharge nozzle 2 without interfering with the discharge nozzle 2 for a certain distance. Therefore, before operating the aerosol valve 130, the discharge nozzle 2 (specifically, the discharge hole 2f of the nozzle portion 2) can be protruded to the outside (protrusion operation). Then, when the top plate 3c of the operation cap 3 abuts on the flange portion 2c of the discharge nozzle 2, the discharge nozzle 2 is pushed down through the operation cap 3 and the aerosol valve 130 is opened (opening operation). When the aerosol valve 130 is opened, the contents are supplied from the aerosol container 110 into the discharge nozzle 2 through the stem 130a. The contents go upward through the internal passage 2d of the discharge nozzle 2, but are blocked by the closing portion 2e, so the content is discharged to the outside from the discharge hole 2f opened to the side. At this time, since the contents are discharged to the outside through the curved control passage CP, the contents are discharged while being swirled around the axis of the nozzle portion 2b. At the same time, since the momentum of the propellant also moves upward, the discharged material discharged later is partially overlapped below the previously discharged content (discharged material), and a spiral (soft cream-like) discharged material Is obtained. The contents are gradually foamed at the stage of being discharged from the aerosol container 110, and are in the form of foam when discharged from the nozzle portion 2b to the outside.

  When the depression of the operation cap 3 is stopped, the aerosol valve 130 is closed, and the discharge of the contents is stopped. At the same time, the operating cap 3 is moved upward by the biasing force of the biasing member 4. Under the present circumstances, the discharge thing adhering to the circumference | surroundings of the nozzle part 2b is scooped down by the top plate 3c of the operation cap 3 from the bottom. That is, the upper surface (top surface) of the top plate 3c located around the opening 3d of the operation cap 3 functions as a skimming surface 3g for skimming the discharge material. When the operation cap 3 returns to the original position before the projection operation, the discharge material remains on the top surface of the operation cap 3, and the discharge nozzle 2 is covered again by the operation cap 3.

  In the aerosol product 100 configured as described above, since the discharge nozzle 2 is covered by the operation cap 3 before the operation, there is no need to separately prepare a cap for protecting the discharge nozzle 2. Moreover, since the contents can be discharged with the operation cap 3 attached, it can be easily used with one hand. In particular, simply depressing the operation cap 3 can perform a projecting operation for projecting the discharge nozzle 2 from the operation cap 3 and an opening operation for opening the aerosol valve 130, and if the depression is stopped, skimming of the discharged matter and the ejection nozzle 2 It is very convenient because the storage of is done automatically. In addition, since the discharge material is scooped up from the discharge nozzle 2 by the top surface of the operation cap 3 which is substantially orthogonal to the axial direction of the discharge nozzle 2, the shape of the discharge material (especially the shape on the outer peripheral side) The shape of the discharge can be enjoyed for a long time. Furthermore, even if the contents remaining in the stem 130a are gradually discharged with time even if the discharge operation is stopped, even if a so-called afterdraw occurs, the discharge nozzle 2 is not operated by the operation cap 3 unless the operation is performed. Because it is covered, it does not become dewy, and it can keep its appearance good.

  FIG. 3 shows another aerosol product 101. In the aerosol product 101, the discharge member 11 is provided with a lock mechanism LM that prevents an erroneous operation of the operation cap 31. FIG. 3A is a view seen through the inside of the operation cap 31 so that the lock mechanism LM can be easily understood.

  The lock mechanism LM includes a groove 31a provided on the inner peripheral surface of the operation cap 31, and a protrusion 51a which protrudes from the outer peripheral surface of the cover member 51 and is fitted in the groove 31a of the operation cap 31. Specifically, the groove 31a is removed from the lock section 31b extending in the horizontal direction, the operation section 31c extending upward from one end of the lock section 31b, and the other end of the lock section 31b to the lower end of the operation cap 31 When the projection 51a is in the lock section 31b or the removal section 31d, the operation of the operation cap 31 is restricted, and the operation cap 31 is pushed down only when the projection 51a is in the operation section 31c. (See FIG. 3B). Four lock mechanisms LM are provided at equal intervals in the circumferential direction.

  In the aerosol product 101 of the above configuration, as described above, since the lock mechanism LM is provided, erroneous operation can be prevented. Further, when the operation cap 31 is pulled up, the operation cap 31 does not rotate carelessly, so the shape of the discharged material is not easily broken. When the operation cap 31 is to be removed from the aerosol container 110, the protrusion 51a may be positioned in the removal section 31d and pulled up. When the protrusion 51a is not located in the removal section 31d, the operation cap 31 does not come off the aerosol container 110, and it is possible to prevent the operation cap 31 from being detached unexpectedly.

  Besides, in the aerosol product 101, the container body 121 does not have the neck portion 120c. The operation cap 31 is substantially dome-shaped, and the scoop surface 3g is also substantially dome-shaped. Further, in accordance with the top plate shape of the operation cap 31, the flange portion 21c of the discharge nozzle 21 also has a substantially dome shape. The cover member 51 has a substantially truncated cone shape. Although the biasing member 4 such as a coil spring is not provided, it may be provided. With respect to the nozzle portion 21 b, a spiral twist is further added to the nozzle portion 2 b of FIG. 2, and the discharge material is more easily swirled. Further, four discharge holes 2f are provided. About the other composition, since it is substantially the same as that of the above-mentioned aerosol product 100, the same numerals are attached and detailed explanation is omitted.

  FIG. 4 shows yet another aerosol product 102. In the aerosol product 102, the operation cap 32 of the discharge member 12 includes a brush 32b.

  Specifically, the operation cap 32 includes a cylindrical base 32a whose upper end is closed, and a brush 32b provided on the upper surface of the base 32a. The outer peripheral surface of the base 32a is provided with a recess 32c for applying a finger at the time of operation. Further, vertical grooves 32 e extending in the vertical direction are provided on the inner peripheral surface. In addition, a protrusion 52a provided on the outer peripheral surface of the cover member 52 is fitted in the vertical groove 32e, and the operation cap 32 is inadvertently rotated at the time of operation (at the time of depression and at the time of pulling up). It functions as a rotation restriction mechanism RM to suppress. The brush 32 b is flocked on the upper surface of the base 32 a and has its tip pointed upward.

  By the way, a through hole 32f is provided at the center of the upper surface of the base 32a substantially circular in plan view. Then, before the operation, the discharge nozzle 22 protrudes from the through hole 32f. Therefore, the length of the nozzle portion 22b is longer than that of the discharge nozzle 2 of FIG. Also in the brush 32b, there is no hair at a position corresponding to the through hole 32f, and an opening 32d through which the discharge nozzle 22 can be inserted is formed. However, the tip of the brush 32 b is located above the tip of the discharge nozzle 22 before the operation. Therefore, before the operation, the discharge nozzle 22 does not protrude outside, and is covered by the brush 32 b which is a part of the operation cap 32.

  In the aerosol product 102, when the operation cap 32 is pushed down, the discharge nozzle 22 protrudes from the inside of the brush 32b to the outside through the opening 32d (protrusion operation). When the operation cap 32 is further depressed, the top plate 3c of the base 32a abuts on the flange portion 2c of the discharge nozzle 22, and the stem 130a is depressed. As a result, the aerosol valve 130 is opened and the contents are discharged from the discharge hole 2f of the discharge nozzle 22. Is discharged from the outside (opening operation). Thereafter, when the operation cap 32 is pulled up, the discharge material B attached to the outer periphery of the discharge nozzle 22 can be skimmed off by the upper surface of the brush 32b, that is, the skimming surface 32g. The operation cap 32 is simply put on the aerosol container 110 and can be easily removed. Therefore, for example, the operation cap 32 can be removed from the aerosol container 110, and the discharge material B can be applied to the object. In addition, the operation cap 32 can be cleaned easily. About the other composition, since it is substantially the same as that of the above-mentioned aerosol product 100, the same numerals are attached and detailed explanation is omitted.

  As mentioned above, although typical embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to change variously within the scope of this invention, and to carry out. For example, the lock mechanism LM and the rotation restricting mechanism RM may be applied to the discharge member 1 of FIG. The groove 31a corresponding to the operation section 31c of the lock mechanism LM and the vertical groove 32e of the rotation restricting mechanism RM do not have to be vertical but may be inclined. Further, as the biasing member 4, in addition to a coil spring, an elastic body such as rubber may be used. The biasing member 4 may be applied to the discharge member 12 of FIG. In addition, although the discharge material is skimmed with the top surface 3g of the operation caps 3, 31 and 32, it may be skimmed directly by hand. For example, when the hands and fingers are placed on the top surface so as to surround the openings 3 d and 32 d and the operation caps 3, 31 and 32 are depressed as they are, the contents are discharged onto the hands and fingers.
